javascript wait between each for loops

i wanna wait between each for loop for 3 seconds, i have tried lots of algorithms but none of them worked, can anyone help?

for (i = 0; i < members.length; i ++) {
  console.log(members[i].username+" "+i);
  if (!members[i].can(Discordie.Permissions.General.KICK_MEMBERS, guildthingy)) {
    var dm = members[i].openDM();
    console.log(members[i].username+" "+i+" "+dm);
    dm.then(function (value) {
      value.sendMessage(message);
      console.log("MESSAGE SENT");
    }, 
    function (value) {
      console.log(value);
    });
  }
}

You can do it like this. 

for (i = 0; i < members.length; i ++){
    (function(i){
        setTimeout(function(){
         console.log(members[i].username+" "+i);
        if (!members[i].can(Discordie.Permissions.General.KICK_MEMBERS, guildthingy)){
            var dm = members[i].openDM();
            console.log(members[i].username+" "+i+" "+dm);
            dm.then(function (value){

                    value.sendMessage(message);
                console.log("MESSAGE SENT");
            }, function (value){
                console.log(value);
            });

        }

        }, 3000 * i);//time in milliseconds
    }(i));
}

The setTimeout function, would apply the delay.

The immediately invocated anonymous function(IIAF), is to get the current value of i in the loop. Since javascript binds the variable i late, all the callings of the function provided in the setTimeout would get the same parameter i if it was not for that IIAF. The latest one.
